<Snipped quote by Guardian Angel Haruki>
Also consider the dialect of primordial based on which elemental plane. It's already supposed to be a harsh language. Terran, dialect of the dao and residents of the plane of earth, is probably a bit more guttural.
That is true!
I could see Aquan including whistles, clicks, and singing similar to dolphins. It's also probably very rhythmic and relies on intonations.
